U.S. officials requested the extradition of seven high-ranking FIFA officials arrested in Switzerland in May

A Swiss probe into corruption allegations surrounding the next two World Cups has grown

(CNN)A former FIFA official being held in Switzerland as part of a corruption scandal has been extradited to the United States, officials said Thursday.

Jeffrey Webb, a former FIFA vice president and onetime head of CONCACAF, the soccer governing body for North America and the Caribbean, arrived in New York on Wednesday, a law enforcement source told CNN.

No court appearance has been scheduled, the source said.

Earlier, the Swiss Federal Office of Justice said a FIFA official had been extradited, but it didn't name the official. The official was handed over to U.S. police escorts in Zurich.

Webb, 50, was banned by FIFA, which has headquarters in Switzerland, from "football-related activities," after he was indicted in May in the United States. He had been on the governing group's executive committee since May 2012.

May 14, 2010 – A turbulent period for FIFA began in May 2010 when the world's governing body for soccer was presented with official bid documents by Australia, England, Netherlands/Belgium, Japan, South Korea, Qatar, Russia, Spain/Portugal and the United States for the 2018 and 2022 World Cups. During the ceremony at its Swiss headquarters, FIFA announced dates for inspections of the bidding nations from July-September.

May 16, 2010 – British newspaper Mail On Sunday reveals that English bid leader David Triesman (pictured here with soccer star David Beckham) was secretly recorded making comments about alleged attempts by Spain and Russia to bribe referees at the imminent 2010 FIFA World Cup.

November 29, 2010 – Issa Hayatou from Cameroon (pictured) is one of three FIFA officials -- the others Nicolas Leoz from Paraguay and Ricardo Teixeira from Brazil -- who are named in a BBC program which alleges they took bribes from the International Sports and Leisure (ISL) marketing company who secured World Cup rights in the 1990s. A day later, Hayatou says he is considering legal action against the BBC. All three would have voted on the hosts for the 2018 and 2022 World Cups. The International Olympic Committee's Ethics Commission later looks into the claims against Hayatou -- as he was an IOC member. It finds he had personally received a sum of money from ISL as a donation to finance the African Football Confederation (CAF)'s 40th anniversary and recommends he be reprimanded. In 2013, an internal investigation finds Leoz and Teixeira accepted illegal payments from ISL but says the acceptance of bribe money was not punishable under Swiss law at the time. Its report says that as both have resigned their positions with FIFA further steps over "the morally and ethically reproachable conduct of both persons" are superfluous.

May 10, 2011 – Just a few weeks before FIFA's presidential vote, former English Football Association chairman David Triesman testifies at a UK parliamentary enquiry into England's failed 2018 bid. Under the cover of parliamentary privilege, Triesman accuses FIFA Executive Committee members Warner, Leoz, Teixeira and Worawi Makudi of trying to secure cash and privileges in return for their vote. In other evidence submitted to the committee from the Sunday Times, it was alleged that FIFA vice-president Hayatou along with fellow Executive Committee member Jacques Anouma has been paid $1.5 million to vote for Qatar as the 2022 World Cup host. All those accused, and the Qatar Football Association, strenuously deny the allegations.

May 26, 2011 – FIFA announces it will investigate Warner (pictured), who ran the CONCACAF federation covering Central and North America, and Mohamed Bin Hammam, head of the Asian Football Confederation, over bribery allegations. It follows a report by fellow Executive Committee member Chuck Blazer alleging that they paid $40,000 worth of bribes to secure the support of members of the Caribbean Football Union. They deny the claims, with Warner promising a "tsunami" of revelations to clear his name. Bin Hammam claims the accusations are part of a plan to force him to withdraw as a candidate for FIFA's presidency. He is incumbent Blatter's only opponent in FIFA's presidential election due to be held June 1.

May 27, 2011 – FIFA says it will expand its corruption probe to include Blatter, after Bin Hammam claimed Blatter knew about cash payments he was accused of giving to national football association in exchange for pro-Hammam votes during Qatar's 2022 World Cup bid. Blatter maintains that the allegations are "without substance," and two days later is exonerated by FIFA's Ethics Committee.

May 29, 2011 – But FIFA's Ethics Committee upholds the complaints against Bin Hammam (pictured) and Warner. Bin Hammam is effectively barred from standing in the FIFA leadership election. Warner's tsunami turns out to be an email, where secretary general Valcke seems to suggest that Qatar "bought" the right to host the 2022 World Cup. After initially threatening legal action, Qatar withdraws its complaint when Valcke explains he was referring to Qatar's large, and legal, campaign budget, rather than bribes. Warner faces no further action following his resignation and the presumption of innocence remains.

June 1, 2011 – Despite a last minute attempt by the English FA to postpone the vote -- a proposal which garnered just 17 out of the available 208 votes -- Blatter is re-elected for a fourth term as president of FIFA at the 61st FIFA Congress at Hallenstadion in Zurich. He vows to learn from past mistakes and undertake a reform agenda.

March 30, 2012 – FIFA announces its executive committee has approved proposed changes to its Ethics Committee, splitting it into two entities -- one to investigate allegations and another to rule on them. It follows a report by the Independent Governance Committee (IGC) commissioned after Bin Hammam's ban, that found FIFA's past handling of corruption scandals had been "unsatisfactory."

April 24, 2012 – The Council of Europe, a watchdog that oversees the European Court of Human Rights, criticizes Blatter in a damning report into FIFA's handling of bribery allegations. The report says it would be "difficult to imagine" that the FIFA president would have been unaware of "significant sums" paid to unnamed FIFA officials by sports marketing company International Sports and Leisure (ISL) in connection with lucrative contracts for World Cup television rights. However it makes no allegations that he had any involvement in corruption.

January 9, 2013 – FIFA imposes a worldwide lifetime ban from football on 41 players from Korea who became embroiled in match-fixing activities in their domestic league, extending a ban handed down by the Korea Football Association (KFA) in 2011. The charges relate to alleged match-fixing in Korea's domestic K-League competition. All but one case were centered on offering or accepting bribes to throw matches.

March 11, 2013 – FIFA says executive committee member Vernon Manilal Fernando of Sri Lanka has been suspended at the request of Garcia and Eckert, co-chairs of the investigatory and adjudicatory bodies of the Ethics Committee respectively. No details of his alleged transgression were released, but FIFA said the decision was based on alleged violations of its Code of Ethics, including conflicts of interest, offering and accepting bribes, bribery and corruption, "in order to prevent the interference with the establishment of the truth with respect to proceedings now in the adjudicatory chamber." He is later given a lifetime ban, which he unsuccessfully appeals to the Court of Arbitration for Sport.

April 30, 2013 – An internal investigation by FIFA's Ethics Committee clears Blatter of misconduct in the bribery scandal, but his predecessor, Brazilian Havelange, resigns as honorary president for his part in the scandal. Havelange and former executive committee members Teixeira and Leoz were all found to have accepted illegal payments from former marketing partner International Sports and Leisure (ISL) between 1992 and 2000.

June 13, 2014 – German footballer Franz Beckenbauer, the only man to win the World Cup as captain and coach, is provisionally suspended from any football-related activity for 90 days for failing to cooperate with a FIFA corruption investigation. FIFA says Beckenbauer had been asked to help with its Ethics Committee's probe into allegations against Qatar 2022 and the World Cup bidding process. Beckenbauer tells German media that he did not respond to questions by the chairman of the Ethics Committee's investigatory body because they were in English and he did not understand them.

December 17, 2014 – Garcia resigns as chairman of the investigatory body of the Ethics Committee, following FIFA's decision to throw out his appeal after he complained about the way his report into the World Cup bidding process had been summarized by Eckert.

May 27, 2015 – At the request of U.S. officials, Swiss authorities raid FIFA's headquarters in Zurich and arrest seven people. Meantime, the U.S. Department of Justice announces the unsealing of a 47-count indictment detailing charges against 14 people for racketeering, wire fraud and money laundering conspiracy. They include FIFA officials accused of taking bribes totaling more than $150 million and in return provided "lucrative media and marketing rights" to soccer tournaments as kickbacks over the past 24 years. Separately Switzerland announces its own investigation into the awarding of the World Cup bids to Russia in 2018 and Qatar in 2022.

Earlier this month, U.S. officials requested the extradition of seven high-ranking FIFA officials arrested in Switzerland in May. They are suspected of taking bribes worth over $100 million in connection with soccer tournaments.

A Swiss probe into corruption allegations surrounding the next two World Cups has grown to include 81 acts of suspicious financial activity now under investigation, Andre Marty, a spokesman for the office of the attorney general, told CNN via email in early July.

He confirmed that all reports were in relation to the ongoing investigation into the allocation of the 2018 -- scheduled to be held in Russia -- and 2022 -- in Qatar -- editions of the World Cup, FIFA's flagship tournament.

Calls this month by CNN to the Qatar 2022 Supreme Committee for Delivery and Legacy, the organizing committee for the 2022 tournament, went unanswered, and at the time of writing the Football Union of Russia had not responded to CNN requests for a statement.

Both Russia and Qatar, however, have publicly denied any wrongdoing with regards to the bidding processes of the two tournaments.

Expanded investigation

The investigation was originally focused on 53 cases, Michael Lauber, the Swiss attorney general, said in June.

Lauber also said, in announcing the initial cases, that he was unconcerned if the investigation produced "collateral damage" in terms of the two countries' right to host their respective tournaments.

Should instances of corruption be proven, the bidding process for the next two World Cups could be reopened, senior FIFA official Domenico Scala has previously said.

A controversial leader – FIFA president Sepp Blatter's 2011 remarks on racism in football -- that on-pitch abuse can be solved with a handshake -- were just one of a series of controversial quotes to be attributed to the head of world soccer.

Tighter shorts for women? – In 2004, Blatter -- seen here with Brazil star Marta -- angered female footballers with his suggestion for how the women's game could be made more appealing. "They could, for example, have tighter shorts," said the Swiss. "Let the women play in more feminine clothes like they do in volleyball."

Football slavery? – In 2008 Blatter was ridiculed after defending the desire of Manchester United's highly-paid star Cristiano Ronaldo to join Real Madrid. He said: "I think in football there's too much modern slavery in transferring players or buying players here and there, and putting them somewhere." In 2013 he had to apologize to Ronaldo after a bizarre impersonation of the Madrid star.

Goal-line technology U-turn – Blatter performed a U-turn on the use of goal-line technology and apologized to the English Football Association after an incorrect decision during the 2010 World Cup. Despite replays showing a shot from England's Frank Lampard had clearly crossed the line in the last-16 clash with Germany, the goal was not awarded.

"Refrain from sexual activity" – In December 2010, Blatter was heavily criticized for suggesting gay football fans should "refrain from sexual activity" if they wished to attend the 2022 World Cup in Qatar, where homosexuality is illegal. Blatter later apologized and said it had not been his intention to offend or discriminate.

Winter World Cup? – Blatter clashed with fellow members of FIFA's executive committee when he suggested the 2022 FIFA World Cup could be played in January to avoid high temperatures in Qatar. He said the move would "protect the players and also the spectators." Qatar flatly rejected Blatter's suggestion at the time, but FIFA is now reviewing whether to adopt it.

Charges dropped – Blatter faced a criminal investigation after winning the 2002 FIFA presidential election, being accused of financial mismanagement by 11 former members of the ruling body's executive committee, including his 1998 election rival Lennart Johansson, right. However, prosecutors dropped the case due to a lack of evidence.

We need to talk about Kevin – In January 2013, AC Milan midfielder Kevin-Prince Boateng led his team off the pitch after being subjected to racist chanting. His actions were hailed across the world. But Blatter was more cautious about the issue, refusing to support the move. "I don't think you can run away, because eventually you can run away if you lose a match," he said in an interview with a newspaper in the UAE. "This issue is a very touchy subject, but I repeat there is zero tolerance of racism in the stadium; we have to go against that." Others, like AC Milan president Silvio Berlusconi, have disagreed with him. "I am of the opposite view (to Blatter)," said Berlusconi. "I thanked and congratulated my players for their decision to leave the field."

The Swiss investigation is proceeding alongside a probe launched by the U.S. Justice Department. The scale of the two operations was brought to light when several high-profile officials were arrested in May as part of an early-morning raid at a luxury hotel in Zurich ahead of FIFA's world congress.

FIFA president Sepp Blatter, who was re-elected to a new five-year term just days after his executive ranks were decimated by the arrests, later announced he would be stepping down once a successor could be found, though he has not been arrested or indicted.

"Culture of corruption"

Richard Weber, head of the IRS criminal investigation division, told reporters following the arrests that the defendants "fostered a culture of corruption and greed."

"This really is the World Cup of fraud, and today we are issuing FIFA a red card," he said.
